Monitoring biomarkers related to inflammation and oxidative stress is critical in dogs because parvovirus causes both inflammatory and antioxidant alterations. The aim of this study was to investigate inflammatory and antioxidant changes caused by canine parvoviral enteritis to better understand the oxidative stress process related to this disease. Thus, the total thiol, native thiol, disulfide, and ischemia-modified albumin levels of Canine parvovirus infected symptomatic puppies and healthy puppies were examined. Using the results of complete blood counts, the blood serum thiol-disulfide homeostasis and ischemia modified albumin levels of the puppies with Canine parvoviral enteritis (n = 65) and the healthy …

This study investigated whether abdominal ultrasonography, a frequently used examination method in clinics and hospitals, causes stress in dogs. For the study, 10 healthy dogs were used. Following general examination, intravenous catheters were placed in the V. cephalica accecorius of the dogs and blood specimens were collected to obtain serum and plasma samples (minute 0). After a 30- min break, ultrasonography was applied following shaving of the abdominal region. Serum and plasma samples were collected from the intravenous catheters at the 5th, 15th, and 20th minutes of the ultrasonographic examination during which the urinary bladder, left kidney, spleen, stomach, liver, …

Oxidative Stress In Calves With Enzootic Pneumonia, Mustafa Özbek, Cumali̇ Özkan
Turkish Journal of Veterinary & Animal Sciences
This study was performed to evaluate the oxidative stress in calves with enzootic pneumonia. Ninety calves that were 2?6 months old were used in this study. Ten of these calves were healthy and used as the control group, while 80 were diagnosed with enzootic pneumonia according to the clinical examinations. The biochemical results showed that total oxidant status (TOS), nitric oxide (NO), malondialdehyde (MDA), and sialic acid (SA) levels were higher in calves with enzootic pneumonia than in the control group. While there was a statistically significant increase in TOS, MDA, and SA concentrations, there was not any statistically significant …

Modern laying hens show fast reduction in egg production rate after 60 weeks of age, which is associated with the decline in ovarian function. The aim of this study was to examine the influence of massive ovulation on the oxidation state and ovarian function in hens. In total, 48 Jing Hong hens aged 17 weeks were randomly divided into high ovulation (HO) and low ovulation (LO) groups. The LO hens were exposed to 6 h of light per day (6 L:18 D) up to 32 weeks to delay the initiation of egg production and then were switched to 16 L:8 …

Turkish Journal of Veterinary & Animal Sciences
Increased lipid peroxidation due to reactive oxygen species (ROS)-induced oxidative stress has been demonstrated in the neoplastic mammary tissue of dogs with malignant mammary tumors. Dietary factors implicated in ROS production may influence mammary cancer incidence or prognosis. Balanced diets (as commercial dog food is considered) may be more protective against oxidative damage than homemade diets. The purpose of this preliminary study was to compare the extent of lipid peroxidation, as evidenced by thiobarbituric acid-reactive substances (TBARS) and \alpha-tocopherol concentration in the neoplastic mammary tissue, among dogs with mammary cancer fed with different kinds of diet (commercial or homemade). Eighteen …

Medicinal plants, especially rich in polyphenolic compounds, have been suggested to be chemopreventive on account of antioxidative properties. Salvia officinalis L., an aromatic and medicinal plant, is widely used in folk medicine and is well known for its antioxidant properties. Therefore, the present study was designed to investigate the antioxidative, possible genotoxic, and antigenotoxic potency of S. officinalis extract against cyclophosphamide (CYP)-induced oxidative stress and genotoxicity in Wistar albino rats. Animals were orally dosed with S. officinalis extract (50, 100, and 150 mg/kg body weight) for 7 days before the administration of a single intraperitoneal dose of CYP (40 mg/kg …

Accidental industrial spills may lead to a high concentration of toxic metals in the aquatic environment, as well as affecting freshwater ecosystems with acute and chronic toxicity. Of all aquatic species, fish are particularly sensitive to waterborne contamination and are recognized as bioindicators for water quality monitoring. The objective of the present study was to evaluate the biochemical changes of the enzymatic defense systems in fresh water fish, the common carp (Cyprinus carpio L.), when they are exposed to a heavy metal contaminated aquatic system. The fish were systematically exposed to heavy metal solutions such as cadmium, lead, nickel, and …

This study was carried out to determine the effect of single dose cadmium chloride (CdCl_2) administration on the possible development of oxidative stress by measuring malondialdehyde (MDA) levels in the liver, kidney and blood serum of male and female rats. For this purpose 80 animals (14-16 weeks old) were initially divided into two 2 groups according to sex, each containing 40 rats. Then both were divided into 5 equal treatment groups [0 (control) 0.5, 1, 2 and 4 mg/kg CdCl_2 body weight by subcutanous injection, respectively]. The blood serum and tissues of the liver and kidney were collected after 24 …

The objective of this study was to investigate ruminal fluid and whole blood oxidant-antioxidant status in normal and fauna-free small ruminants. Forty male Ramlıç lambs, a local breed in the Afyon area, with an average body weight of 32-36 kg and approximately 210 days old were used. The lambs were divided equally into 4 groups (faunated (F), defaunated (D), faunated + urea (FU) and defaunated + urea (DU)). Malondialdehyde (MDA) and glutathione (GSH) concentrations in the ruminal fluid and blood were measured. In comparison with the controls, all parameters were significantly higher in the fauna-free animals. The ruminal fluid MDA …

Trichloroethylene (TE) is an environmental toxic solvent hazardous to human and domestic animals and well known in the industrial sector. The purpose of this study was to determine whether oral TE plays a role in lipid oxidation and tissue damage. Fourteen dogs were treated with an oral toxic dose of 0.5 ml/kg T.E. The acute changes that occurred in creatine kimase (CK), malondialdehyte (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were investigated in blood samples taken before application and 8, 24, 48, 72 and 168 hours after treatment. SOD and GSH-Px activities decreased, protein, albumin and alcalen phosphate did …
